Layer Feed Formula Manual: Layer feed formulas revealed! Follow these recipes and see your egg production soar by 20%, while reducing costs by 0.5g/cent!
“Why are other people’s eggs as thick as coins, while yours are as thin as a cicada’s wing?” 90% of egg production declines are due to poor nutrition. This article reveals the golden formula used by a large-scale chicken farmer with 30 years of experience, covering the entire four-season nutrition plan from brooding to laying to culling, making it easy for even beginner chicken farmers to follow along!
一．Core Formula for the “Three-Stage Nutrition” of Layers
| Growth stage | energy（kcal/kg） | crude protein（%） | calcium（%） | Key raw material combination |
| Brooding period (0-6 weeks) | 2850-2950 | 18-20 | 1.0 | Corn 58% + soybean meal 28% + fish meal 5% + premix 4% |
| Growing period (7-18 weeks) | 2700-2800 | 15-16 | 1.2 | Corn 62% + bran 15% + rapeseed meal 8% + bone meal 2% |
| Egg laying period (19 weeks+) | 2750-2850 | 16-18 | 3.8-4.2 | Corn 60% + soybean meal 22% + rock powder 8% + soybean oil 2% |
Formula Tips:
Children’s eggs are high in egg white, young eggs are energy-efficient, and laying eggs requires a lot of calcium!
二.Four low-cost alternatives (don’t worry if raw material prices rise)
1. Soybean meal is in short supply → Use these three alternatives:
Cottonseed meal (≤8%, requires 0.1% lysine)
Rapeseed meal (≤5%, add choline to prevent liver damage)
Insect protein (Black soldier fly powder, replace 50% of soybean meal)
2. Corn is too expensive → Use alternative energy sources:
Wheat (requires enzyme preparation, replaces 30% of corn)
Rice bran (fresh! ≤10%)
Cassava residue (use after fermentation, replaces 15% of corn)
3. Stone powder substitute
Shell powder (38% calcium content, crushed to 2mm)
Eggshell powder (homemade: boil eggshells in water, then dry and crush)
三.The “Three Treasures for Increasing Efficiency” of Experienced Chicken Farmers (Add 10 yuan to the cost per ton and the efficiency will double)
1. Egg Yolk Color Enhancer
Chili Powder (0.3%): Increases yolk redness by two levels
Marigold Powder (0.5%): Natural source of lutein
2. Gut Guardian
Clostridium butyricum (200g/ton): Reduces feed-to-egg ratio by 0.15
Zeolite Powder (1.5%): Absorbs mycotoxins
3. Heat Stress Relief Formula
Summer Additions: Baking Soda 0.3% + Vitamin C 200g/ton
Feeding Hours: 4 AM – 6 PM (Avoid high temperatures)
四.The recipe pitfalls that 90% of people have fallen into (bitter and tearful lessons!)
NO: Rapidly increasing calcium during the rearing period → Ureteral stones!
YES: Gradually increase calcium to 3.5% 2 weeks before egg production
NO:Using only one feed throughout the entire process → Premature aging + rectal prolapse!
YES:Switch to peak feed when egg production reaches 5%
NO:Using moldy corn as a makeshift → Egg production plummets!
YES:Aflatoxin testing is mandatory (≤20μg/kg)
五.Practical Guide for Self-Mixed Feed
1. Equipment List
Crusher (crush corn to 2-3mm)
Mixer (coefficient of variation ≤5%)
Electronic scale (error ≤50g/ton)
2. Mixing Order
First add 70% corn, then soybean meal, then premix.
Mix Time: 15 minutes for vertical mill, 5 minutes for horizontal mill.
3. Quality Self-Inspection
Protein Test: Urease rapid test strips
Uniformity: Take 10 samples, chloride ion variation ≤10%
